When I learned from Chapter 12 "struts2 authoritative guide>, I encountered the problem of integrating freemarker.
If struts labels are used, an error is reported.
<#assign s =JspTaglibs["/WEB-INF/struts-tags.tld"]>
If the freemarker label is used, an error is reported.
Classnotfound: org. Apache. stuts. Views. jsp. UI. autocompletertag., this class cannot be found.
After reading the foreign website, I found that:
I was using struts-tags.tld file from earlier version of Struts. And that is why it was referencing the autocompletertag class.
ClassNotFoundException: org.apache.struts2.views.jsp.ui.AutocompleterTagSo to solve this problem, just un-jar the struts2.2.3-core. jar file, and get the struts-tags.tld file from META-INF folder, and put it in your resources (WEB-INF/struts-tags.tld ).
That is to say, the TLD file I used is wrong with the version of the struts-core.jar. Then I extracted my TLD from the jar file and replaced the old version.
